Description

Technical Field

[0001] The utility model relates to the technical field of orthotics, in particular to a 3D sculptured torso orthosis. Background Art

[0002] The 3D Sculpted Trunk Orthosis is a trunk orthosis manufactured using 3D printing technology. It is a customized medical device used to treat spine-related problems or poor posture, such as scoliosis, kyphosis, kyphosis, and round back.

[0003] After searching, a lumbar orthosis for rehabilitation and conditioning with publication number CN217339020U includes an adjustment mechanism, a wrapping mechanism, a heat dissipation mechanism and a display mechanism. The adjustment mechanism includes: a connecting plate, which is arranged at the top of the wrapping mechanism; a shoulder strap, which is arranged on both sides of the top of the connecting plate; an adjustment strip, which is arranged at the bottom of the middle end of the shoulder strap; a slide, which is arranged inside the bottom end of the adjustment strip; and an adjustment slot, which is arranged inside the slide. When the patient wears it, the outer splint wraps the inner splint and uses nylon straps to fit it, which is also convenient for the user to adjust the tightness. The overall fixing effect is good, the adhesion is strong, and the fit is good. The waist is fixed and the stability and support of the lumbar spine play a good role. However, the above technical solution still has the following shortcomings when it is actually used:

[0004] The prior art provides an inner splint and an outer splint, which are connected by a guide hole and an adjusting screw. When the size of the orthosis needs to be adjusted, the user needs to first align the matching tool with the adjusting slot on the adjusting screw, then screw the screw to make the inner and outer splints in a loose state, and then pull the outer splint to adjust the size. In this process, the user needs to screw multiple screws, and each screw needs to be ensured to be screwed into place, which brings complexity and tediousness to the adjustment operation, and increases the difficulty and time of the user's operation. Secondly, in order to ensure the correction effect of the orthosis, the outer splint is generally required to be symmetrically arranged. In this way, when adjusting the size of the orthosis, it is also necessary to ensure that the moving distance of the outer splints on both sides is the same. Since the outer splints on both sides are fixed by a number of separate screws, the user also needs to observe the moving distance of the two outer splints at the same time during adjustment, which further increases the tediousness of the adjustment operation and affects the user's convenient use experience.

[0005] Therefore, it is necessary to design a 3D sculpted trunk orthosis to solve the above problems. Utility Model Content

[0029] The specific working principle of the utility model is as follows:

[0030] When the size of the orthosis needs to be adjusted, the user pulls the fixing plate 9 outward to separate the block 10 from the slot 11. At this time, the spring 8 is in a stretched state. The fixing plate 9 is then rotated to rotate the shaft 7. Under the mutual limiting action of the shaft 7 and the sleeve 5, the rotation of the shaft 7 can drive the sleeve 5 and the gear 6 to rotate, thereby driving the two racks 4 to move away from or towards each other, and the moving distances are the same. The fixing plate 9 is then released after the block 10 is aligned with the slot 11. Under the action of the spring 8, the block 10 can be inserted into the slot 11. The part realizes the fixation of the rotating shaft 7, and then realizes the fixation of the position of the orthosis 1. In the above process, the wearer does not need to use tools to screw multiple screws to adjust the size of the orthosis, which simplifies the operation process and increases the convenience of adjustment. Secondly, the moving distances of the two racks 4 are the same, which makes the two orthosis plates 1 at the same distance from the extension plate 2, ensuring the symmetry of the orthosis, and then contributing to the correction and restoration of the trunk, ensuring the comfort of the orthosis, and eliminating the need for the user to separately adjust the positions of the orthosis plates 1 on both sides, thereby improving the efficiency of adjustment.
